THey would both work. I rent them tho. Trash pumps are built for that stuff and it's easier to buy the insurance policy when you rent and take it back for another one if it quits than to fix your's when it breaks. Also placing the intake hose in a bucket suspended from an truck inner tube will keep the intake hose clear of most debris. If you are pumping from a shallow area you may need to dig a 4x4 x4 sump hole to keep an adequate amount of water available to the intake or you'll wreck the pump. Better buy a bunch of fuel cans too! Depending on your time availability and budget you may want to rent something mounted on a trailer from Godwin Pumps. They can get you a pump that will fill that field in short order. Most have around 100 +HP diesel motors and ungodly flow rates.

The only reason we are looking at these pumps instead of renting is for times like late season we could use these to keep running and keep out hole thawed out. Most likely we are renting a large pump for now though, we will look into buying one maybe next year.
